Axial play of constant speed gear 2 tapered roller bearing

mm

0,02...0,08

1

Place spacer ring (5) on bearing collar.

2

Preload tapered roller bearings using  adjusting sleeve (3). While doing so, turn constant speed gear 2 gearwheel (6) several times.

 The tapered roller bearings are sufficiently preloaded when the 2 (6) becomes difficult to turn.

3

 Loosen adjusting sleeve (3) slightly.

4

Turn constant speed gear 2 (6) several times while tapping the constant speed gear 2 (6) using a plastic mallet.

 This releases stresses.

5

 Screw on adjusting sleeve (3) again slightly by hand.

6

 Attach dial indicator (1) to  adjusting gauge (2).

 If the pin of the  dial indicator (1) is too short, use the  extension.

7

 Attach adjusting gauge (2) to  adjusting sleeve (3) so that it slides.

8

Use  dial indicator (1) to measure to collar of main shaft (4).

9

 Set dial indicator (1) to zero.

10

Use  dial indicator (1) to measure to spacer ring (5) or to collar of tapered roller bearing in constant speed gear 2 gearwheel (6).

 Results in dimension A.

11

Calculate thickness of shim (8) to be inserted.

 Dimension A - 0.20 mm = thickness of shim to be inserted.

12

Pull off constant speed gear 2 gearwheel (6) using suitable pull-off device up to an end play of approx. 1.0 mm.

13

Fit calculated shim (8) and pressure plate (7) on collar of journal.

14

 Attach dial indicator (1) to  adjusting gauge (2).

15

 Attach adjusting gauge (2) so that it slides on  adjusting sleeve (3).

16

 Position dial indicator (1) on ground surface of constant speed gear 2 gearwheel (6) and turn constant speed gear 2 gearwheel (6) approx. 20 times.

17

 Set dial indicator (1) to zero.

18

Turn constant speed gear 2 gearwheel (6) briefly to right/left and while simultaneously pushing up/down (A, B), read off bearing play on  dial indicator (1).

 Do not use a screwdriver or assembly lever to press the constant speed gear 2 gearwheel (6) up and down.
This can result in measurement errors.

19

If there is any deviation, correct using appropriate shim (8) and repeat measuring procedure.

 An end play near the lowest tolerance limit should be aimed for.
